SLEEVE OR COLLAR BUTTON.

SPECIFICATION forming part of Letters Patent No. 288,964, dated Nove1nb:r 27', 1883.

(No model.)

To @ZZ whom, it may concer/t:

Be it known that we, SILAs J. ALLEN and Jiiirns B RICHARDSON, both citizens of the United States, residing in the city and county of Providence, in the State of Rhode Island, have invented a new and useful Sleeve and Collar Button and Stud, of which the following is a specification.

Our invention relates to sleeve and collar buttons and studs in which there is a movable hinged post actuated by a helical spring, and adapted to operate in conjunction with a iixed post, to form automatically-interlocking arms to secure the button in the garment.

The objects of our invention are to provide a button of cheap and simple construction, not liable to get out of order, and one which will automatically and securely lock itself in the garment. rIlhese objects are fully attained by the special construction and arrangement of the parts illustrated in detail in the accompanying drawings, in which Figures l and 3 are front and side views. Fig. 2 is a vertical section online :r w. Figs. 4 and 5 are sectional front and side views of the back plate and the fixed post attached thereto, and Fig. 6 shows the oscillating post with its pinion and helical spring.

A is the rim of the button, of the usual form, and inade in the ordinary manner, and provided with a stone or other setting, S. I) b is t-he lining or back plate, provided with a chamber formed by depressing it at b b, and having securely attached to it the fixed post C. -We slot the lining or back plate, I), at o, to admit of t-he introduction through it of the oscillating post B, which is slotted at k and open-slotted at a, and provided with a pinion, p, by which it is journaled upon the upper face of the back plate, b. After the introduction of the post B through the slot o, the pinion p is inserted in the post and provided with a helical spring, e, which will then occupy the open slot a. The fixed post C and the oscillating post B being oppositely curved, upon the introduction of the post B in the slot o the post C will enter the slot 7s. lVe then insert a disk, d, which retains the oscillating post B, helical spring c, and pinion p in place. The whole is then inserted in the rim A, in which the setting S has previously been inserted,and the rim is either burnished or soldered to the back plate, I), and the button is complete. The edge of the slot k adjacent to a is beveled, to 'lit the curve in the post C and act as a stop to the post B.

In practical opcration,to introduce the button into the buttonhole of the garment, the oscillating post B is pressed back until it occupies the dotted-line position shown in Figs. 2 and 3, bringing the outer end of the post C flush with the outer face of the post B. The end of the post B is then inserted in the button-hole, and as soon as the garment has passed over and beyond the end of the post C the spring c, acting upon the post B, will throw it into its normal position, and the two posts thus automatically interlocking will securely retain the button in the garment. The reverse movement will unlock the arms and disengage the button.

It is not necessary in our invention, as .it is in all other detachable buttons heretofore known, to take hold ot' the post to detach or insert the button. It is only necessary to take the button by its head and insert the end of the post B in the buttoirhole, when a slight pressure will force it back to allow the post C to enter the button-hole, when the spring will actuate the post B to automatically lock the button.

IVe are aware that buttons having oppositelycurved posts have been heretofore known; but we claim that an oscillating curved post actuated by a helical spring to lock automatically with an oppositely-curved fixed post was never known or used prior to our invention thereof.

XVe claim as our invention- I. In an automatically-locking button and stud, the combination of a fixed curved post, C, attached to the back plate, b, with an oppositely-curved oscillating post, B, pinioned upon the back plate and actuated by a helical spring, e, and adapted, in conjunction with said post C, to form automatically-interloeking arms to secure the button in the garment,

as shown.

2. The combination 0f :L brick plate, b'Z, slotted at 0, and depressed :it b b', .to form :n chamber, and having :L fixed curved post attached to it, with :m opposiiely-cuived post, B, pinion p, :md helical spring (l, :is shown.

3. The eombnmion 01: the beek plate, l),

pinion p, helical Spring e, :uid post B, openslotted :it (l, as shown.
